Ok...new to forums. I have an idea which is hard to explain and different from all the router table ideas I can see online. What I was thinking, was to make a ply wood box internal dimensions 6"×2" and approx 18" long and open at two ends. Then mounting that onto my miter saw roller bench, just to utilize the rollers to feed into and out of each open end. And then finally mounting the router on top of the box, with an adjustable bed across the width. This would then be used specifically for 6x2 to be feed into to cut rebates. My question is, is it a good idea to encapsulate the 4 sides of the timber when being feed into the router or not?
